Abstract

River and groundwater have been the major sources of drinking and irrigation water supply in the rural and urban area of the region. The annual groundwater withdrawal in the country is 231 Billion Cubic Meter/Year (213 BCM used for irrigation and 18 BCM used for drinking). Groundwater is the preferred as an alternative in most part of the region, which is facing threats due to anthropogenic activities, leading to deterioration of the groundwater quality. This study intends to find the deterioration cause of groundwater near the Kham river basin. For study purpose, the 54-groundwater sample near the Kham River has been collected from different parts of the city. The samples were analyzed for Pre-monsoon and Post-monsoon season for the year 2014 for their pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Sodium (Na), Calcium (Ca) and Magnesium (Mg). Suitability for irrigation was determined on the basis of the diagram of US salinity Laboratory (USSL), Sodium adsorption ratio (SAR), and Percent sodium (PS). Samples have been categorized in left bank and right bank samples and observed that 29.90% (n = 8) groundwater samples along left bank and 14.8% (n = 4) groundwater samples along the right bank are in medium sodium hazard category. According to USSL diagram, nine samples along left bank and thirteen samples along the right bank of the Kham river fall in category C3S4, indicating high salinity and very high alkaline water and addresses.
